*Note: Where several body codes were issued, the production ccolumn indicates the body code reference. ie 1985 4EZ57 Coupe 4EZ67 Convertible**Note: Horsepower figures up to and including 1970
were reported by GM as BHP GROSS. 1971 and after they reported SAE NET
(ie as installed in the car), this explains part of the dramatic drop
in hp figures from 1970-1971. 1971 Gross HP figures were 315 standard
and 330 GS.
